While enable R8 for release build, hilt inject wrong type for member variable - HILT-2.40.1

[larryxiao625]

In debug build, there is no problem for my app. But when isMinifyEnabled = true, I have got an ClassCastException, View after unlocking the apk, I saw @Inject got a wrong type
This is the dex file type

I have got a CurrentDevicAdapter
But in the source file, it should be DeviceInfoAdapter

I have no idea why this problem will occur
I have checkd the mid product for hilt in outputs folder, it is the right type

I just resolve it by adding @keep annotation for the right adapter

Glad you were able to solve the issue but if you think this is still an issue you should file a bug to the R8 / Proguard team here: https://issuetracker.google.com/issues?q=componentid:326788. R8 has optimizations to merge interfaces and reduce classes so it might be related to that.
